Health watchdog completes child catheter scare probe

Last month doctors found wire near the hearts of nine children who had peripheral inserted central catheter lines (PICC line) used to administer chemotherapy drugs and antibiotics.

The soft wire should be removed after guiding the catheter into place.

The Therapeutic Goods Administration on Friday said an investigation had found no inherent flaws with any brands of the PICC, but it was important instructions for use were carefully followed.

Queensland's chief health officer Dr Jeannette Young said no further cases had been found since the nine were identified.

"We've essentially completed our investigation and we don't believe there are any others out there," she told reporters on Friday.

"The main issue that came out of it was that there was a real lack of information about how best to use that product."

The children had been treated at Queensland's Mater Children's and Townsville hospitals.
